➀ Elon Musk proposed a Kasparov vs. Deep Blue-style AI coding contest between xAI's Grok 5 and former OpenAI lead Andrej Karpathy, which Karpathy declined, emphasizing AI as a collaborator;
➁ The challenge follows Karpathy's remarks that AGI remains a decade away and that Grok 5 trails GPT-4 by months, while Musk claims Grok 5 has a 10% AGI probability;
➂ Analysts note Grok 5's credibility hinges on transparent benchmarking akin to DeepMind's competition-grade tests, yet xAI has not yet published formal results.
